6. n channel FAM The result is positive The sample contains Pneumocystis Carinii DNA In this case the detection of a signal in channel VIC JOE Internal control is dispensable as high initial concentrations of Pneumocystis Carini1t DNA can lead to a reduced or absent fluorescence signal of the internal control competition 2 In channel FAM no signal is detected at the same time a VIC JOE signal from the internal Control appears The sample does not contain any Pneumocystis Carinii DNA It can be considered negative In the case of a negative Pneumocystis Carinii PCR the detected signal of the internal control rules out the possibility of PCR inhibition 3 Neither in channel FAM nor in channel VIC JOE is a signal detected A diagnostic statement can not be made Inhibition of the PCR reaction Gentaur Molecular Products Voortsiraat 49 1910 Kampenhout Belgium

8. ts who have undergone bone marrow transplantation 3 Principle of Real Time PCR The principle of the real time detection is based on the fluorogenic 5 nuclease assay During the PCR reaction the DNA polymerase cleaves the probe at the 5 end and separates the reporter dye from the quencher dye only when the probe hybridizes to the target DNA This cleavage results in the fluorescent signal generated by the cleaved reporter dye which is monitored real time by the PCR detection system The PCR cycle at which an increase in the fluorescence signal is detected initially Ct is proportional to the amount of the specific PCR product Monitoring the fluorescence intensities during Real Time allows the detection of the accumulating product without having to re open the reaction tube after the amplification 4 Product Description Pneumocystis Carini real time PCR kit contains a specific ready to use system for the detection of the Pneumocystis Carinii by polymerase chain reaction in the real time PCR system The master contains reagents and enzymes for the specific amplification of the Pneumocystis Carinii DNA Fluorescence is emitted and measured by the real time systems optical unit The detection of amplified Pneumocystis Carinii DNA fragment is performed in fluorimeter channel FAM with the fluorescent quencher BHQI1 DNA extraction buffer is available in the kit and bronchial lavage sample or lung section sample is used for the extraction of the DN
